This is the last weekend to check out Tag the System, an exhibit of different artists' and designers' subway car interpretations. The participants got 2 foot long models of subway cars and were able to go wild. Check out the art here; Gothamist is partial to the Uglydoll version, though it's impractical to actually have an Uglydoll subway car. Tag the System is at the Showroom NYC at 117 2nd Ave, through Sunday, November 21.

And yesterday, the NY Times looking at how far subway graffiti has come, and mentions the Tag the System show as well as the subway maps at Marcoart.
